Design and Analysis of Algorithms

Consider a table B that consists of m integers B [1], B [2] ... B [m]. Design an algorithm to produce a two-dimensional m x m table C such that each element C[i,j] for i <j contains the sum of the B [i] up to the B [j], that is, (B [i] + B [i +1] + ... + B [j]). The values C[i,j] for i >= j are left unspecified, that is, these c
